The Texas Education Agency (TEA) is seeking responses from qualified organizations to provide high-quality supplemental online curriculum in math aligned to the Texas Essential Knowledge and Skills(TEKS). Qualified products should be grounded in researched-based instructional strategies (RBIS) and support implementation alongside Math Tier 1 High-Quality Instructional Materials (HQIM). Products must include language supports for emergent bilingual and multilingual learners and offer RBIS-aligned scope and sequence for ease of district implementation. Through this RFQ, TEA will qualify products to be eligible for TEA-subsidized use by school systems and will pay for product licenses in accordance with access and high-fidelity use by students. Products must provide instructional mastery dashboards accessible at multiple levels (student, classroom, campus, district, and state) to inform instruction and monitor usage. TEA will qualify products based on alignment with TEKS and RBIS, ease of district implementation, and ease of progress monitoring.
